How to use an Excel Datasource with the Enterprise Gateway

[Clark]

I have seen a couple references to limitations in the Enterprise Gateway with Excel Datasources and I'm wondering what the best way would be to make this work.  I have an on-prem Sql Data Source that is working great through the gateway, but as soon as I add an Excel datasource saved in Sharepoint Online, I no longer have the ability to use the Enterprise Gateway.  Do I have to save this on the Sql Server as well?  Is there another way?

Enterprise Gateway only supports files on-prem(SharePoint on-prem).You have 2 options:

1- Use Personal Gateway, with the personal gateway you can combine both online and on-prem data sources. But the limitation is you can no longer do Direct Query and it only supports Schededuled refresh. 

2- Keep using the Enterprise gateway and move your data to SQL Server or what you can do is move the Excel file to a SharePoint on-prem, or in a folder on-prem. Basically have them all available on prem and not mixed.

I tested one by moving to our On-Prem Sharepoint and now it's not available again.  Do I need to create a connection for each folder or file in the gateway?  How does it know to use the gateway for the files that are in our On-Prem sharepoint?
